To provide a continuous transfer food processing apparatus enabling a cleaned state to be inspected easily and manual cleaning work to be conducted easily, and capable of eliminating the concentration of thermal stress and discharging water or a chemical liquid without tilting a heat-insulating tank.

A continous transfer food processing apparatus is provided with a heat-insulating tank 1 formed into vertically split construction having an upper lid 2 and a lower main body 4. A plurality of lifting means 3 capable of horizontally lifting the upper lid 2 to hold it in such a state as to be separated from the lower main body 4 are set on both side faces of the lower main body 4. Further, drainage ditches having an incline descending toward a discharge hole 30 in the longitudinal direction of the bottom of the heat-insulating tank 1 are formed in the bottom of the heat-insulating tank 1 along its longitudinal direction.
